“…Pelvis and proximal femur are among the preferential sites of involvement (up to 70-90%) of Paget's disease, but it is worthy of note that its prevalence is rapidly declining. 23 Metastasis is the most important diagnosis to rule out (both lytic and/or sclerotic). Other differential considerations include multiple myeloma, lymphoma/myelofibrosis, and chronic osteomyelitis.…”

“…Fibrous dysplasia can be thought of as a developmental disorder characterized by replacement of normal bone marrow with benign fibro-osseous tissue. 23 It can be present at any age (most by the age 30). It can either be monostotic (70-80%) or polyostotic (20-30%).…”

“…The femur is usually involved in the monostotic form (although not the bony pelvis, where it is uncommon to present as a monostotic lesion (< 2%); both the femur (90%) and/or pelvis (80%) are usually involved in the polyostotic form. 13,23 The imaging presentation is the same as elsewhere in the body. In the pelvis, typical fibrous dysplasia presents as lesions that are lytic and particularly occur in the iliac bones, even though the matrix is usually variable (lucent to sclerotic).…”

“…13 Aneurysmal bone cysts do not have a specific predilection to the hip and pelvic region (7-9% in the proximal femur, 6% in the ilium, and 2% in the sacrum, pubis, and ischium). 1,4,[13][14][15][16][17][18][19][20][21][22][23][24][25] The imaging presentation is the same as elsewhere in the peripheral skeleton. The best diagnostic clue is the patient's age as well as the presence of an eccentric lytic lesion composed nearly entirely of fluid-fluid levels (notably, fluid-fluid levels are not pathognomic or obligatory; the neocortex can be extremely thin and hardly visible, and progression of this tumor can be very fast) (►Table 6).…”

“…The pelvis and sacrum are common sites. 23 An enostosis may raise suspicion for metastasis in a patient with a known primary tumor. Clinical correlation along with assessment of the tumor markers, metabolic bone profile, and after comparison with prior imaging confirms whether this is a new lesion and to look for interval change.…”

Although it is possible for any osseous tumor or tumorlike lesion to occur in and around the hip and pelvis, there are preferential lesions. Most tumors share many imaging features with those arising elsewhere in the skeletal system, but some may show specific morphological and imaging features. Furthermore, specific criteria and rules of thumb are related to this anatomical area that radiologists should know, which together with the imaging findings and clinical context will lead to a more confident diagnosis.In this article we review the basic anatomical and imaging principles in the hip and pelvis and their diagnostic criteria, describe the most common regional benign and malignant bone tumors and pseudotumors, and highlight their main imaging features and common differential diagnosis while keep this article as relatively simple and straightforward as possible. Soft tissue tumors are beyond the scope of this article.
